iXRecessed Housings:
Recessed Housings
are the
part of the recessed light
that
is installed inside the
ceiling,
but is not visible once
installed and contains the
light
socket. These look like either
a
large metal box with an upside
down cup in the middle, or a
large upside down cup with a
junction box and cord
extending
from it.

Recessed Trims:
Recessed Trims are
the
decorative, visible portion of
the
light
that attaches to the recessed
housing. Trims are generally
round and come in a variety of
trim sizes. The trim is the
circle (or sometimes square)
that surrounds the light
source.
They are generally very simple
in appearance.

Recessed Lighting
Kits:
Recessed Kits
include
both the housing and the trim.

iXNew
Construction recessed
lighting is installed
during construction (before
the sheetrock is installed).
They are installed between
ceiling joists in the attic
space, and typically have two
extending arms to keep them in
place.

Remodel
recessed lighting does not
have the extending arms and is
installed on a
completed home. It is installed from below and is
made to attach directly to the
sheetrock.
